My car has done almost exactly the same battery capacity dance, and it now calculates out to 320 miles range at 27 months, 25k miles.lpickup wrote: ↑Fri Aug 21, 2020 10:37 amI think this is a relative newbie that hasn't had enough time with the car to determine that, like the LEAF, there is an initial drop-off of capacity that flattens out significantly.
Of course I just went to check my own report...it's a bit hard to determine what my loss actually is because while my car nominally started out at 310 miles of range (and TeslaFi actually estimated 315 miles in my earliest reports), a software update was rolled out to my car that extended that range to 325 miles, resulting in a TeslaFi estimate of 318.25 miles. At 13K miles I had my then highest range estimate at 319.66, and then it fell to 297.76 miles in January of this year at about 20K miles. But then, who knows why, but my capacity has recovered, and the latest estimate at 24K miles is now 319.97. So my battery has actually GAINED capacity! Even if you go with a theoretical 325 mile range when new, that's still 1.5% capacity loss on a 2 year old car.
Your breath is wasted on doug. He lurks at TMC until he finds an anecdote that matches his desire to view Tesla in a negative light and trolls here with his 'finding.' If that was not pathetic enough, often he does not understand what he is reading and the 'negative' report is something else.
By the way -- battery capacity measurements are pack temperature dependent. Range in a cold pack will be decreased. I've learned to check battery capacity ONCE a year. In part because it is a very good battery and more frequent checks are a waste of time, and in part to keep environmental variables similar across the trend points. Spring and Autumn checks (for those who just *have* to check more often) would also work OK
